This work follows analysis of the internal wave kinetic equation presented in [1]} and [2]}. That work plays off a scale invariant stationary state of \(n({\bf p}) \propto k^{-3.69}m^{0}\)  in the non-rotating limit, in which \(n({\bf p})\)  is waveaction spectral density and \({\bf p}\)  is a three dimensional wavenumber with vertical component \(m\)  and horizontal wavenumber magnitude \(k\) . That work formally introduces a 'cut' in the spectral domain to separate 'local' from 'extreme scale separated' dynamics and finds that the 'local' dynamics dominate and support downscale transports in both horizontal and vertical wavenumber. The transports are sensibly consistent in magnitude and direction with the Finescale Parameterization.
